The Incremental Capital-Output Ratio (ICOR) is the ratio of investment to growth which is equal to the reciprocal of the marginal product of capital. The higher the ICOR, the lower the productivity of capital or the marginal efficiency of capital. The ICOR can be thought of as a measure of the inefficiency with which capital is used. In most ...
Productivity in economics is usually measured as the ratio of what is produced (an aggregate output) to what is used in producing it (an aggregate input). [1] Productivity is closely related to the measure of production efficiency. A productivity model is a measurement method which is used in practice for measuring productivity.
A high ROI means the investment's gains compare favorably to its cost. As a performance measure, ROI is used to evaluate the efficiency of an investment or to compare the efficiencies of several different investments. [1] In economic terms, it is one way of relating profits to capital invested.
TFP is calculated by dividing output by the weighted geometric average of labour and capital input, with the standard weighting of 0.7 for labour and 0.3 for capital. [3] Total factor productivity is a measure of productive efficiency in that it measures how much output can be produced from a certain amount of inputs.
The MEC and capital outlays are the elements that a firm takes into account when deciding about an investment project. The MEC needs to be higher than the rate of interest, r, for investment to take place. This is because the present value PV of future returns to capital needs to be higher than the cost of capital, C k. These variables can be ...
Return on capital (ROC), or return on invested capital (ROIC), is a ratio used in finance, valuation and accounting, as a measure of the profitability and value-creating potential of companies relative to the amount of capital invested by shareholders and other debtholders. [1] It indicates how effective a company is at turning capital into ...
A number of arguments relating to concerns for efficiency and equity may be found in the literature supporting the taxation of capital income, including (1) Corlett-Hague motives, (2) increases in consumption inequality over the life cycle, (3) heterogeneous preferences, (4) correlation between returns on savings and ability, (5) incomplete or ...
In economics, capital goods or capital are "those durable produced goods that are in turn used as productive inputs for further production" of goods and services. [1] A typical example is the machinery used in a factory. At the macroeconomic level, "the nation's capital stock includes buildings, equipment, software, and inventories during a ...
